Specification of Letters Patent.

Application filed April 23, 1913. Serial No. 763.147.

To all whom it may concern:

Be it known that I, Cumulus A. HAYDEN,

a citizen of the United States, residing at Gorham, in the county ofCoos and State of New Hampshire, have invented anew and useful ImprovedNut and Bolt Construction, of which the following is a specification.

This invention relates to certain improve ments in the construction of abolt and the nut therefor.

An object of the present invention is to provide a bolt with thethreaded portion thereof provided with milled sides and a mutilated nutadapted to ceact with the same to provide means whereby-the nut may bepositioned upon the bolt by a. sliding movement thereon and may then bepartially rotated to thereby engage the mutilated threads of the bolt.

Afurther object is to provide a bolt with milledsides and a mutilatednut whereby in. order'that the nut'may be retracted it is rotatcd untilthe mutilated portion of the nut comesadjacent the milled sides of thebolt at which time the threads of the nut andbolt disengage and the nut.may be then readily. withdrawn from the. bolt.

A further object is to pro ide means whereby the mutilated nut may coaetwith a similar mutilated nut and locked thereto so that the two nutsmay. be tightened against anobject in the manner of "an ordinary boltand nut.

\Vith the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafter doscribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, can he made within'thescope of what isiclaimed, without-departing from the spirit of the inveution. V

In the drawings accompanying this specificationand forming a part theeof the preferable f rm of my invention is illustrated, in which:

As illustrated in Fig. 5-of the'drawings a to procure a. continuity '-ofPatented se as, 1914..

nut 3 with the usual threaded aperture eX- tending therethrough ismutilated as at 4 and 5, which ter'm'refers to a cutting away 7 of aportion of the side walls of the aperture as at l'and 5 whichwhenregistering with the lint milled sides Qof thebolt alscribed, allowsthe nut to readily slide upon the bolt when the flat side of the bolt isin alincmeut with the mutilated portion of the nut and the nut when inthe desired posi-' tion by a slight rotation engages the threads ofthebolt in the ordinary manner. From 'theforcgoing it will be readilyapparent that the nut may be moved into position or retracted therefromby a sliding movement which greatly facilitates the positioning of thenut upon the bolt. In order however that the nut may be tightened bymeans 0! the bolt threads, a second nut 7 is provided similar inconstruction to the nut 3 with the exception that the aperture 8 whichis adapt:

ed to al'ine with the aperture 6 in the first mentioned nut, is shiftedwith relation to the longitudinal axis of the mutilated portion so thatwhen the two nuts are positioned'upon the bolt as illustrated in Fig. 3and a suitable locking'pin passed through the apertures 8 and. 6 thetWo. nuts will be shifted so that the mutilated portion of one nut comesadjacent the threaded .portion' of the ther nutwhich will provide thatone of the nuts ivill always engage the threads of the bolt from whichit will be apparent that the nut 3 may be positioned upon the bolt andmoved longitudinally of the same until the' desired'position thereof isreached after which the nut 7 will he slid upon the engage the threadsof the bolt.

bolt into contact with the nut 3 and the two nuts shifted so that theapertures (Sand 8 will be alined and a suitable locking pin 9inserted'therethrough. A wrench may now be secured to the two nuts andthe same rotated. The two-nuts will act similar to a' single nut withcontinuous threads and therefore a suitable wedging action may beprocured by a rotating of the two nuts.

in order to provide positive locking means for a nut the washer 10 asillustrated in Figs. 6 and 7 of the drawings is provided with an opening11 therein, said opening be' of a size suflicient to pass readily overthe threaded portion of a bolt and the said aperture 11. is-providedwith the lips 12 projecting from the side walls thereof, the said lips12 adapted to contact with the flat milled sides 2 of the bolt and topass between the side walls of the bolt and the side walls of the nut.The projecting lips 12 of the washer are relatively thicker than the Inntion of the bolt which has been removed with the result that the saidlips 12 may project into the mutilated portions 4 and 5 of the nut andwhen so positioned it will be impossible for the nut to rotate in eitherdirec tion as the diameter of the threaded portion of the nut is smallerthan the'combined thicknesses of the bolt and the two lips. In thedrawings, the nuts 3 and 7 have been represented as of the conventionalhexagonal type vbut it is to be noted that the external shape of the nutmay be varied and that the apertures 6 and 8 of the two nuts will be sopositioned that when a securing pin is passed therethrough the externalsurface of the 'two nuts will be in alinement so that a single wrenchmay engage both nuts simultaneously so that the same may be rotated.Also, mention is made of the factv that the two apertures will be sopositioned with relation to the mutilated portion of the nut that whenthe said apertures are in alinement, the threaded portion of one nutwill be in alinement with the mutilated portion of the other nuttothereby obtain a continuous threaded engagement with the bolt by the twonuts. In the practical use of my improved nut and bolt, the bolt ispassed through the material to be secured thereby, which in Fig. 3 ofthe drawings has been represented as being two boards and the nut 3 slidupon the said bolt and into contact with the outer surface of the boardand is then given a slight rotation so as to The nut 7 is thenpositioned to contact with the not 3 and rotated until the apertures 6and Saline, at which time a suitable securing pin is passed through thesame. A wrench may now engage the two nuts and rotate the same with theresult that the nuts will be driven forward into forced contact with theboard and required pressure exerted thereon. The

nuts.

V I I nut having assumed the desired position the pin 9 is withdrawn andthe nut 7 slightly retracted until the mutilated portion thereof alineswith the mutilated portion of the bolt at which time it is readilywithdrawn from the said bolt and the washer 10 is then insei't-ed uponthe bolt with the projecting lips 12 extending between the mutilatedportion of the bolt and the mutilated portion of the not 3, from-whichit will .be apparent that it will be impossible for the nut 3'to rotatein either direction which would resultin the out 3 becoming disengagedfrom the-thread ed portion of the bolt." In order'yto prevent thewz-isher 10 from shifting longitudinally the aperture 13 is formedtherein and a suitable cotter pin or equivalent means passed through theaperture 13 and the alining aperture 6 of the nut 3 and the sameeifectually holds the said washer in position. lVhcn it is desired toremove the nut 3 from the bolt the washer is first withdrawn and the nut3 then slightly rotated either in a forward or reverse direction untilthe mutilated portion thereof comes into alinement with the mutilatedportion of the bolt at which time the nut may be readily retracted boltin this ease being the same as herei I heforedescribed. The number ofnuts whi b may be assembled upon the bolt for the tightening of thefront nut may be varied and the positioning ofthe apertures therein mayalso be varied so that efficient holding means is obtained upon thethreaded portion of the bolt. that the two nuts will be left upon thebolt and the'washer inserted behind the last one. The nuts may bequickly and easily slid into position upon the bolt and by a slight ro'tating of the same suitably tightened. Also when. it is desired toremove the nuts a slight rotation ofthe same after the two nuts havebeen disengaged one from the other, allows in some cases it will beunderstood the same to be readily retracted from the bolt and slidtherefrom. Mention is also made of the fact that the nuts 3 and 7 mayhave a plurality of the apertures 6 formed therein as illustrated inFig. '5, which remark also holds true with respect to the washerillustrated in Fig. 6. Mention is also made of the fact that the inneropening of the aperture 6 is enlarged so that the cotter pin may beinserted with the head por tion therein which will prevent any chance ofthe cotter pin being disengaged from the Having thus fully described theinvention What I claim to be new and original with me l.
